Question

I believe my most recent commit in Mercurial has become corrupt. I cannot commit anything anymore, nor can I rollback.

I ran hg verify which suggested I should run hg recover. I then ran hg recover as suggested and I am now getting the error:

abort: index 00manifest.i is corrupted!

According to this post: http://osdir.com/ml/version-control.mercurial.general/2007-03/msg00099.html I should be able to remove the last 64 bits from the 00manifest.i file and start working again.

Is this correct and how would I go about doing so?

PS. Everything I have done so far has been on a clone of the original repository.

Many thanks,

Andy

You can truncate 00manifest.i using a Python console:

$ python
>>> with open("00manifest.i.orig", 'rb') as fp:
...     data = fp.read()
>>> with open("00manifest.i", 'wb') as fp:
...     fp.write(data[:-64])

First, the file is read in binary mode. data is just a string. Then slicing is used to write back all but the last 64 bytes, again in binary mode.
